I have experimented with this cartridge as well, and I was quite impressed. At the time I was comparing it to a much more expensive Clearaudio Maestro V2, and the Maestro had more detail and depth. However, a few minutes into listening with the Shelter I forgot about the comparison and just sat back and listened. It's a very easy cartridge to listen to, and if the Maestro breaks I will happily drop the Shelter in its place without feeling that I'm missing much at all.
